6.When a programmer writes a class definition to implement an interface, he/she must write the method body for at least one of the method headings specified in the interface TRUE OR FALSE?
7. Declaring a formal parameter's type as T is the same thing as declaring the parameter's type as Object. TRUE OR FALSE?

Homework Answers
4. Java allows for the use of generic typing to do away with all
type checking of parameters to methods. TRUE OR FALSE ?
Answer: True
5 How many interfaces can a class implement?
Answer: one or more than one(65535).
6.When a programmer writes a class definition to implement an interface, he/she must write the method body for at least one of the method headings specified in the interface TRUE OR FALSE?
Answer: False(must write the method bodies for all of the method headings specified in the interface)
7. Declaring a formal parameter's type as T is the same thing as
declaring the parameter's type as Object. TRUE OR FALSE?
Answer: False(T is a generic type. Meaning it can be substituted by
any qualifying object at runtime. )
8. What is the access type for all methods in an interface.
(spelling and case matter).
Answer: All methods in an interface are public, even if you leave
out the public keyword in the method declaration.

1. When a sub class object is created, when is the call to the super class constructor made? How does a programmer call the super class constructor from the sub class? What do all classes indirectly extend? What methods does every class inherit from the Object class? 2. When writing methods in a sub class, how can those methods call the methods from the parent class? 3. Which class is more specific, a super class or a sub class? 4. ...

Java program. Code the following interfaces, implement them, and use the interface as a parameter, respectively: a. An interface called Printable with a void print() method. b. An interface called EmployeeType with FACULTY and CLASSIFIED integer data. The value of FACULTY is 1 and CLASSIFIED is 2. a. A class called Employee to implement the two interfaces. Its constructor will initialize three instance data as name, employeeType, and salary. Implementation of method print() will display name, employeeType, and salary; salary...

Lab #4 – Recursive Methods for Generic ArrayList ----- JAVA The problem Use recursion to implement some list functionalities on an ArrrayList of generic type using type parameters in method definition Our goal for this lab is to continue using the divide and conquer approach of splitting a list into its head and tail and keep recursing on the tail (which happens to be smaller). However, instead of trying the approach on a string (a list of characters) we would...

Java programming The purpose of this problem is to practice using a generic Urn class. NOTE: Refer to the code for the ArrayStack class from Chapter 12. Use that code as a starting point to create the Urn class, modifying it to remove the methods in the ArrayStack class (push, pop, etc) then add the methods described below. Also change the variable names to reflect the new class. For example the array name should NOT be stack, instead it should...

JAVA Problem: Coffee do not use ArrayList or Case Design and implement a program that manages coffees. First, implement an abstract class named Coffee. The Coffee class has three member variables: coffee type, price, and store name. The Coffee class has an abstract method name ingredient. Make sure to add all necessary setters and getters as well as other methods. The class Coffee implements an interface HowToMakeDrink. The interface has the following method: public interface HowToMakeDrink { public void prepare ();...

The purpose of this problem is to practice using a generic Jar class. write in drjava Create a generic class, called Jar, with a type parameter that simulates drawing an item at random out of a Jar. For example the Jar might contain Strings representing names written on a slip of paper, or the Jar might contain integers representing a random drawing for a lottery. Include the following methods in your generic class, along with any other methods you’d like:...

***JAVA: Please make "Thing" movies.
Objective In this assignment, you are asked to implement a bag collection using a linked list and, in order to focus on the linked list implementation details, we will implement the collection to store only one type of object of your choice (i.e., not generic). You can use the object you created for program #2 IMPORTANT: You may not use the LinkedList class from the java library. Instead, you must implement your own linked list...

*****************************In Java***************************************In Java***********************************In Java************************* In this problem, you will implement various algorithms operating on binary search trees. We have provided with you a standard implementation of a generic BST in BinarySearchTree.java. Note that this class is an abstract class, which means that some of its methods are not implemented. In previous assignments, you have implemented interfaces which specified methods that you needed to write. Very similarly, an abstract class is a class with some unimplemented methods (it can be thought...

10.3 Example. When you first declare a new list, it is empty and its length is zero. If you add three objects—a, b, and c—one at a time and in the order given, to the end of the list, the list will appear as a b c The object a is first, at position 1, b is at position 2, and c is last at position 3.1 To save space here, we will sometimes write a list’s contents on one...
